Free: Contests & Raffles.
Usually somebody is giving the dog attention after he licks them. As long as he see's licking people as a way to get attention he will keep doing it. I also give my chocolate lab a light swat to the nose to discourage it. She still licks a little, mostly because a couple people in the house still give her attention after licking, but it is much better than it was. Neither tobasco or sour green apple spray worked for my dog, she actually liked it.
